Product details
Overview
1V5KE82CA from Taiwan Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge clamping in power and signal lines. It features a 77.9–86.1 V breakdown voltage (VBR), 70.1 V reverse stand-off voltage (VRWM), 1500 W peak pulse power (1 ms), 13.3 A peak pulse current (IPPM), and 113 V clamping voltage (VC) - used to protect industrial I/O, AC/DC power inputs, and telecom line interfaces against ESD and lightning-induced transients.
For engineers reviewing the 1V5KE82CA datasheet, 1V5KE82CA pinout, 1V5KE82CA application, or 1V5KE82CA equivalent, key selection criteria include its bi-directional clamping symmetry, low incremental surge resistance, sub-1 μA leakage at 70.1 V, UL 94V-0 molding compound, and compatibility with JEDEC-standard DO-201 mechanical mounting and reflow profiles.
Technical Context
The 1V5KE82CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages. Its bi-directional construction ensures symmetrical clamping in both polarities, making it suitable for AC-coupled or floating signal paths without polarity concerns.
It delivers 1500 W peak pulse power under 10/1000 µs waveform per IEC 61000-4-5, with thermal stability up to 175 °C junction temperature and robust mechanical reliability including JESD201 Class 2 whisker resistance and pure tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V - defines minimum and maximum voltage at which avalanche conduction begins reliably at 1 mA test current |
| VRWM | 70.1 V - maximum continuous reverse operating voltage before significant leakage occurs |
| VC @ IPPM | 113 V - clamped voltage during 13.3 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak surge power handling capability for 1 ms pulse, critical for lightning immunity |
| IPPM | 13.3 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | 175 °C - maximum junction temperature, supporting operation in high-ambient industrial environments |
| Package | DO-201 - industry-standard axial-leaded package with 0.090 g mass, UL 94V-0 rated epoxy |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional variants; for bi-directional 1V5KE82CA, polarity marking is not functional - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity - no fixed polarity required in circuit layout |
| Leads (both) | Current path to PCB pads | Pure tin-plated, solderable per J-STD-002; lead length affects thermal derating - 0.375" length supports 5 W steady-state dissipation at 75 °C ambient |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Lower PPPM (600 W), smaller SMB package, VRWM = 75 V, VC = 121 V | Not suitable for 1500 W lightning-level events; better for space-constrained board layouts | Select when footprint area is critical and surge threat level is limited to IEC 61000-4-5 Level 2 |
| 1N6291A | Same manufacturer, DO-201 package, but unidirectional; VRWM = 64.1 V, VC = 92 V | Requires correct polarity placement; unsuitable for AC or floating differential lines | Choose only for DC-biased single-polarity circuits where lower clamping voltage justifies directional constraint |
Compared with SMBJ75CA and 1N6291A, the 1V5KE82CA provides higher surge robustness in the same legacy DO-201 form factor, with bi-directional symmetry eliminating polarity dependency - essential for AC line and telecom interface designs requiring consistent clamping regardless of transient polarity.

FAQ
What is the clamping voltage of the 1V5KE82CA under a standard 10/1000 µs surge?
The 1V5KE82CA has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 13.3 A under the 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - a critical parameter for ensuring downstream components remain within safe operating limits.
Is the 1V5KE82CA unidirectional or bi-directional, and how does that affect circuit placement?
The 1V5KE82CA is a bi-directional TVS diode, indicated by the "CA" suffix. Its symmetrical avalanche structure allows either terminal to serve as anode or cathode depending on transient polarity. This eliminates polarity sensitivity during PCB layout - unlike unidirectional variants such as 1N6291A, the 1V5KE82CA can be placed across AC lines, differential data pairs, or floating nodes without orientation constraints.
What is the maximum operating temperature for the 1V5KE82CA, and how does it impact thermal design?
The 1V5KE82CA supports a maximum junction temperature (TJ) of 175 °C, enabling reliable operation in high-ambient environments such as industrial control cabinets or under-hood automotive locations. When designing heatsinking or airflow, note that its steady-state power dissipation derates linearly above 75 °C ambient - at 125 °C ambient, usable PD drops to ~2.5 W using the published derating curve.
Does the 1V5KE82CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE82CA is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use pure tin plating - satisfying environmental directives for industrial, telecom, and consumer electronics markets requiring strict material declarations and supply chain traceability.
How does the 1V5KE82CA compare to the 1V5KE75CA in terms of voltage ratings and application suitability?
The 1V5KE82CA has a higher VRWM (70.1 V) and VBR (77.9–86.1 V) than the 1V5KE75CA (VRWM = 64.1 V, VBR = 71.3–78.8 V), making it more appropriate for 72–80 V nominal systems like certain telecom power rails or 48 VDC industrial buses. Both share identical 1500 W PPPM, DO-201 package, and bi-directional construction - the choice depends strictly on system operating voltage margin and clamping headroom requirements.
